Inferring on the Galapagos island, Darwin discovered birds with differently shaped beaks. What might this tell you about the eating habits of birds? Explain.

That the different bird species evolved to have different diets. For instance, the species with skinnier beaks could've evolved to have a affinity for small, elusive insects. While their brethren developed bigger beaks to carry nuts, eat rodents or whatever else was in-abundance on the island.
